JavaFX apps will not run from a Browser on Windows 7 64 bit
Problem: After installing Java 6 or Java 7 and the Java FX Runtime on Windows 7 64 bit, you can not launch JavaFX applications from your browser. Any attempt to launch an application results in a request from the browser to install Java. Which is silly because it is already installed. Or is it?
Solution: Most web browsers are actually 32 bit applications. Consequently, you must install the 32 bit version of the Java Runtime Edition (JRE) and the 32 bit version of the JavaFX runtime. The first will install the needed Java plugin for your browsers. The second makes JavaFX available for 32 bit apps. After the install, restart your browser and voila, everything should work fine.
